When liquid rises and approaches the sensing surface, the coupling of the liquid’s parasitic capacitance with the sensor’s static capacitance causes a measurable change. A builtin highaccuracy control IC converts this minute variation into a differential signal and analyzes it with a proprietary algorithm, triggering an output once the liquid level reaches the set threshold.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003eUltraCompact \u0026amp; Rugged Design\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eMeasuring just 6.1mm in thickness, this miniature liquid level sensor can be easily embedded into tight spaces.
